Miniature rose plant named ‘POULhi009’

ABSTRACT

A new miniature rose plant which has abundant, yellow flowers and attractive foliage. The variety successfully propagates from softwood cuttings and is suitable for year round production in commercial glasshouses. This new and distinct variety has shown to be uniform and stable in the resulting generations from asexual propagation.

Classification: Botanical: Rosa hybrida ‘POULhi009’. Commercial: miniature rose.

SUMMARY OF THE INVENTION

The present invention constitutes a new and distinct variety of miniature rose plant which originated from a controlled crossing between ‘POULsabel’, described and illustrated in U.S. Plant patent application Ser. No. 10/136,451 dated Apr. 29, 2002, which is a continuation of 09/607,333, dated Jun. 30, 2000, and ‘KORstoffein’ described and illustrated in U.S. Plant Pat. No. 11,242, issued on Feb. 22, 2000. The two parents were crossed and the resulting seeds were planted in a controlled environment. The new variety is named ‘POULhi009’.

The new rose may be distinguished from its seed parent, ‘POULsabel’ by the following combination of characteristics:

1. The flowers of ‘POULsabel’ are dark red, whereas those of ‘POULhi009’ are yellow.

2. ‘POULsabel’ has 25 to 30 petals, while ‘POULhi009’ has 40 to 45 petals.

The new variety may be distinguished from its pollen parent, ‘KORstoffein’ by the following combination of characteristics:

1. The flowers of ‘KORstoffein’ are peach-colored, while those of ‘POULhi009’ are yellow.

2. The leaves of ‘KORstoffein’ are matte, whereas those of ‘POULhi009’ are glossy.

The objective of the hybridization of this rose variety for commercial culture was to create a new and distinct variety with unique qualities, such as:

1. Uniform and abundant flowers;

2. Vigorous and compact growth;

3. Year-round flowering under glasshouse conditions;

4. Suitability for production from softwood cuttings in pots;

5. Durable flowers and foliage which make a variety suitable for distribution in the floral industry.

This combination of qualities is not present in previously available commercial cultivars of this type and distinguish ‘POULhi009’ from all other varieties of which we are aware.

As part of their rose development program, L. Pernille Olesen and Mogens N. Olesen germinated the seeds from the aforementioned hybridization and conducted evaluations on the resulting seedlings in a controlled environment in Fredensborg, Denmark.

‘POULhi009’ was selected by the inventors as a single plant from the progeny of the hybridization in May of 1999.

Asexual reproduction of ‘POULhi009’ by cuttings and traditional budding was first done by L. Pernille and Mogens N. Olesen in their nursery in Fredensborg, Denmark in October of 1999. This initial and other subsequent propagations conducted in controlled environments have demonstrated that the characteristics of ‘POULhi009’ are true to type and are transmitted from one generation to the next.

1. Stem showing opened flowers, branching and the attachment of leaves, buds, and peduncles;

2. Flower bud, partially opened bud, and open bloom;

3. Flower petals, detached;

4. Sepals, receptacle, and pedicel;

5. Two bare stems exhibiting thorns;

6. Leaves.

DETAILED DESCRIPTION OF THE VARIETY

The following is a description of ‘POULhi009’, as observed in its growth in 3 year old budded plants in a field nursery in Jackson County, Oreg. Color references are made using The Royal Horticultural Society (London, England) Colour Chart, 1995, except where common terms of color are used.

For a comparison, several physical characteristics of the rose variety ‘POULra001’, a rose variety from the same inventors described and illustrated in U.S. Plant Pat. No. 13,487 dated Jan. 21, 2003 are compared to ‘POULhi009’ in Chart 1.
